Question
Shalom aleichem Rabbi Lauffer. Thank you for answering my last question. Rabbi Chaim Kanievsky famously paskened that no Batei Midrash or yeshivos should be closed during the pandemic, only to retract his psak soon after when thousands became infected because of his mistaken psak. Can Rabbi Kanievsky be relied upon anymore in Torah matters, given his incorrect psak on this matter, which he was forced to retract? Thanks a lot.

Question
The Hasmoneans usurped throne and priesthood. The Hasmoneans claimed the throne of Judah. Since they were not descendants of Judah (and therefore not from the House of David), the kingship was not their right. The Hasmoneans also made a family member high priest, which is the prerogative of a branch of Aaron’s family to which they did not belong. However, I read that the Hasmoneans were descended from Aaron of the tribe of Levi. Please explain how the Hasmoneans had no right to the priesthood. Who were the Hasmoneans descended from?
